On the mod releases I put out the Leveler's Chamber that kinda sorta works for TTW. Leveler's House for FNV mostly works as well.
My idea is a mod that combines both of these into one with the TTW features like sorting NV items in the chamber and sorting F3 items in the leveler's house and having one teleport orb for both leveler's houses.
I don't know what such a undertaking would entail, but considering I like to use these two places as a merchant/repair shop and a starter house, it'd be nice for them to be combined to take full advantage of TTW.
Just a thought.
